TECHNICAL FIELD

The present invention relates generally to the field of bicycle pedalsand more specifically relates to a magnetic mountain bike pedalassembly.

BACKGROUND

Many mountain bicycle riders are passionate about the mountain bicycleriding experience. They pay attention to the functioning of each pieceand want to use the best equipment possible. For many such persons, thepedal is of paramount concern.

Because the pedal is one of the points of connection between the rideand the mountain bike, the right or wrong pedal can change how the riderinteracts with both the bicycle and the trail. Whether the rider isgoing off a jump, pedaling hard, or coasting along, the pedal, togetherwith the grips and the seat, are one of the most important points ofconnection on a mountain bike. And, the choice of pedal can also havelong term effects on a rider's knees, back, and feet.

Consequently, mountain bike pedal design is of great importance.Typically, there are two categories of mountain bike pedals: “flats”where the user's foot simply presses against the pedal, or “clipless,”which despite the name refers to a pedal wherein a shoe can removablyclip to the pedal for added connection. Many serious riders prefer theconstant connection provided by clipless pedals, but others prefer thefreedom of flats. Indeed, persons with bad knees may prefer flats sothey can better control the movement of their knees.

The problem with clipless pedals is intertwined with their benefit: itis cumbersome or difficult to disconnect the shoe from the pedal. So itcan be seen that a need exists for a pedal with the control andconnection of the clipless pedal, but that also provides the freedom andnatural movement of the flat pedal.

Various attempts to solve this problem have been made. One such attemptcan be seen with respect to U.S. Pat. No. 5,473,963, incorporated byreference in its entirety herein, which generally discloses a magneticbicycle pedal using six Neodymium Iron Boron (NdFeB) magnets in thepedal. While this disclosure does generally provide for a magneticpedal, it not only requires Neodymium Iron Boron (NdFeB), rather thansimply Neodymium, it also requires at least six such magnets in acoordinated arrangement, which could presumably be easily damaged andrendered nonfunctional in harsh conditions.

Another attempt can be seen with respect to U.S. Pat. No. 9,545,972,incorporated by reference in its entirety herein, which generallydiscloses a magnetic mountain bike pedal. While this disclosure doesprovide for a single Neodymium magnet in each of the pedal and the shoeelements of the disclosure, this disclosure fails to provide for zinc orstainless steel protective plating for the magnets (providing only forsteel plating), which changes the magnets' protection, in some wayspossibly for the worse.

Yet another attempt can be seen with respect to U.S. Patent ApplicationPublication No. 2016/0137274 A1 incorporated by reference in itsentirety herein, which generally discloses another magnetic shoe/pedaldevice having an angled cylinder element on the shoe that may bereceived into the pedal. While theoretically enabling magnetic joiningand unjoining, the design of the cylinder element not only makes thisdisclosure more likely to be damaged, walking on such a device may alsoaffect the user's musculature.

Various attempts have been made to solve the problems which may be foundin the related art but have thus far been unsuccessful. A need existsfor a new magnetic mountain bike pedal assembly to avoid theabove-mentioned problems.

SUMMARY

It is to be understood that in the present disclosure, all embodimentsare provided as illustrative and non-limiting representatives of manypossible embodiments. In addition, the terms “is,” “can,” “will,” andthe like are herein used as synonyms for and interchangeable with termssuch as “may,” “may provide for,” and “it is contemplated that thepresent invention may” and so forth.

The present invention relates to a magnetic mountain bike pedal thatovercomes the deficiencies of the prior art. It is contemplated that thepresent invention may provide a magnetic mountain bike pedal assemblythat enables rapid and secure attachment and unattachment as between ashoe and a mountain bicycle pedal.

For purposes of summarizing, certain aspects, advantages, and novelfeatures of the present invention are provided herein. It is to beunderstood that not all such aspects, advantages, or novel features maybe provided in any one particular embodiment. Thus, the disclosedsubject matter may be embodied or carried out in a manner that achievesor optimizes one aspect, advantage, or novel feature or group offeatures without achieving all aspects, advantages, or novel features asmay be taught or suggested.

In view of the foregoing disadvantages inherent in the known art, thepresent invention provides a novel magnetic mountain bike pedalassembly. The general purpose of the present invention, which will bedescribed subsequently in greater detail, is to provide a mountain bikepedal with a magnetic element, which may preferably be composed of atleast one element of Neodymium in isolation or in combination with oneor more other elements, located either in a mountain bike pedal, a shoe,or both.

In one embodiment, the present invention may provide for a bindingsystem for a shoe to a pedal. The magnetic center of the pedal allowsthe shoe to maintain constant contact with the pedal. More specifically,the present invention's pedal element(s) use at least one, in someembodiments two, Neodymium magnets that may be axially magnetized. Theyare magnetized through the length or thickness of the pedal which arethe strongest points of the flat faces. The magnets are incorporatedinto at least one stainless steel shell in the center of the pedal.There is a spindle going through the center of the stainless steel shellholding it in the center of the pedal but also allowing it to float. Byallowing the magnet housing to float, it maintains better connectionbetween shoe and pedal. It also the geometry of the knees to operate ina much more natural motion with less stress being put them than may bedisclosed in the prior art. There is also a stainless steel wall orfloor between magnet ‘A’ and magnet ‘B’. The stainless steel shellcreates a cup around each magnet that absorbs the magnetic field on oneside and forces it toward the opposite direction. This creates a doublepull at one end of each magnet. The stainless steel shell doubles as avery tough layer of protection from harsh environments. Zinc (Zn)plating may be used to protect the exposed magnet faces. The magneticpull that is created by the neodymium magnets is attracted to a ferrousmetal cleat (approx. 35 mm×50 mm) that attaches to the sole of amountain bike shoe that is fitted with, by way of illustration and notlimitation, the SPD system. This system creates and maintains a bettercontact between shoe and pedal while allowing the rider to wear a flatshoe. Axially magnetized neodymium magnets' strongest pull come fromnorth and south poles. So, by moving the heal of the shoe east or west,or in some embodiments any direction laterally, decreases the pull andenables the shoe to release from the magnet.

The foregoing is but one of many examples of how the present invention'sshoe element may be disengaged from the present invention's pedalelement.

The contemplated benefits of the present invention include the fat thatusing the Neodymium magnetics as a binding system may give riders morefreedom without being locked in, while still able to pull up on thepedal for efficiency. It also may allow more “float” than thetraditional clipless pedal, which in some embodiments may allow for amore natural movement and less stress on the user's knees. Lastly, theaction of locking into and disconnecting from the pedal may be mucheasier and user-friendly with the present invention than with atraditional clipless pedal. One example of many in which this may bedesirous is if and when a user finds the trail to be difficult, the usercan disconnect the user's feet from the pedal with much more ease thanwith the traditional clipless pedal. This allows much more confidencewhich, it is contemplated, provides users with a much more joyful ride.

It is also contemplated that the present invention, including withoutlimitation the present invention's neodymium magnetic platform pedalelements, encompasses the best attributes of the ‘clipless’ and ‘flat’pedal and creates a pedal that is in the middle. By doing this, itallows the rider to ride with more confidence and less wear and tear onthe body.

Additionally, the present invention can provide value to users who ridebikes indoors, such as spin bikes in gyms. With the present invention,users can wear workout shoes to the gym and not need to carry extraclipless specific shoes that are not general-walking or workoutfriendly, due to their hard slippery soles. Users can also derivebenefit from the present invention in any circumstance where personsride bicycles, such as for those who ride bicycles as part of theircommute to work or when they are running general errands. Additionally,BMX bike riders can greatly appreciate the use of this kind of pedal, aswell as users of road bikes.
